Psalms 102:9

Ashes are his bread (cf. Lam 3:16), inasmuch as he, a mourner, sits in ashes, and has thrown ashes all over himself, Job 2:8; Eze 27:30. The infected שׁקּוי has שׁקּוּ = שׁקּוּו for its principal form, instead of which it is שׁקּוּי in Hos 2:7. "That Thou hast lifted me up and cast me down" is to be understood according to Job 30:22. First of all God has taken away the firm ground from under his feet, then from aloft He has cast him to the ground - an emblem of the lot of Israel, which is removed from its fatherland and cast into exile, i.e., into a strange land. In that passage the days of his life are כּצל נטוּי, like a lengthened shadow, which grows longer and longer until it is entirely lost in darkness, Psa 109:23. Another figure follows: he there becomes like an (uprooted) plant which dries up.

Some think that David penned this psalm at the time of Absalom's rebellion; others that Daniel, Nehemiah, or some other prophet, penned it for the use of the church, when it was in captivity in Babylon, because it seems to speak of the ruin of Zion and of a time set for the rebuilding of it, which Daniel understood by books, Dan 9:2. Or perhaps the psalmist was himself in great affliction, which he complains of in the beginning of the psalm, but (as in Ps. 77 and elsewhere) he comforts himself under it with the consideration of God's eternity, and the church's prosperity and perpetuity, how much soever it was now distressed and threatened. But it is clear, from the application of Psa 102:25, Psa 102:26, to Christ (Heb 1:10-12), that the psalm has reference to the days of the Messiah, and speaks either of his affliction or of the afflictions of his church for his sake. In the psalm we have, I. A sorrowful complaint which the psalmist makes, either for himself or in the name of the church, of great afflictions, which were very pressing (Psa 102:1-11). II. Seasonable comfort fetched in against these grievances, 1. From the eternity of God (Psa 102:12, Psa 102:24, Psa 102:27). 2. From a believing prospect of the deliverance which God would, in due time, work for his afflicted church (Psa 102:13-22) and the continuance of it in the world (Psa 102:28). In singing this psalm, if we have not occasion to make the same complaints, yet we may take occasion to sympathize with those that have, and then the comfortable part of this psalm will be the more comfortable to us in the singing of it. A prayer of the afflicted, when he is overwhelmed, and poureth out his complaint before the Lord.
